Explore the process of building a Telegram bot using Apache Kafka, Go, and ksqlDB in this conference talk from GOTO 2020. Learn how to ingest, filter, enrich, aggregate, and query data using only Kafka, without the need for additional datastores. Follow along with a hands-on demonstration of creating a bot that provides key/value lookups driven by a materialized view on Kafka event streams. Discover the capabilities of ksqlDB for processing data and understand the key design elements of this approach. Gain insights into the benefits of this architecture and its potential applications in real-world scenarios.
